Subject: builtin-revert.c: release index lock when cherry-picking an empty commit
X-Git-Tag: v1.6.2.1~8^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=0d66e95903a5c2567baa61cc7299ce865abe41b1;p=git.git

builtin-revert.c: release index lock when cherry-picking an empty commit

When a cherry-pick of an empty commit is done, release the lock
held on the index.

The fix is the same as was applied to similar code in 4271666046.
